Despite all of the flaws... I found myself hooked once I sat down to play it myself (instead of watching someone else play) =X
I think the thing that's upsetting people the most is how much potential was wasted by certain decisions Bethesda made~
I think I've pinpointed the exact reason why it just puts me off so much and that's the black and white decision making. It's a HUUUUGE step up from the standard "you must report this to the guards... or let me handle it hehehe" choices that maybe 2 or 3 Oblivion quests give you but everything is so clear and concise.
"Hey you. You're new here, aren't you. Don't fuck up or I'll rip your fucking eyes out and shove them so far up your fucking ass you'll see shit coming."
*I'm a good person. See, there's a little halo above my head!
*Fine, whatever.
*FUCK YOU! FUCK YOU AND THE TOWN YOU BLEW OUT OF RAAAAAAGE
I did like how if you convinced the guys in Tenpenny towers to allow the Ghouls in they ended up
killing everyone regardless. That whole "do good but end up failing anyways" is the kind of black humor I expect from Fallout.
